We are pleased to introduce the M-90D Desktop Microphone and M-90MS Microphone Stand Kit for YAESU HF transceivers.
The M-90D and M-90MS utilizes a dynamic microphone element that is finely tuned to deliver rich low to mid frequency response desirable for a clear and concise conversation.

Using a windscreen cover and a directional microphone element, the structure of the microphone of the M-90D and M-90MS is designed to concentrate voice input from the front while reducing ambient noise from the side.

Built-in Low-Cut filter creates clear and crisp audio characteristics by shaping the low frequency response (cut off at 340Hz, -6dB/octave).

An isolation transformer is integrated in the circuit board in order to enhance the audio quality.

The M-90D and M-90MS* are compatible with all YAESU HF transceivers equipped with the round 8-pin microphone connector or the 8-pin modular microphone connector.

M-90D Desktop Microphone
The PTT of the M-90D uses three Air-Cylinder tubes similar to the Reference Microphone M-1. This provides solid and smooth extended operation. A simple one-touch PTT keylock button is placed directly above the PTT key for those long rag chews.
*M-90D does not require the SCU-53 to connect to the transceiver equipped with the round 8-pin microphone connector.

The M-90D is available June, 2021.

M-90MS Kit Microphone Stand Kit
M-90MS Kit is a Microphone Stand Kit which includes W3/8 Nut, a handheld PTT controller and a microphone head which can be mounted on a microphone stand. Microphone stand is not included. This kit requires a commercially available microphone stand. The M-90MS Kit requires an optional SCU-53 cable to connect to transceivers equipped with the round 8-pin microphone connector.*

The M-90MS Kit is available July, 2021.
